BARREL-HOOP MACHINE.

SPECIFICATION forming part of Letters Patent No. 313,207, dated March 3, 1885.

Application tiled January 8, 1885. (No model.)

To all whom it may concern.-

Be it known that I, ALBERTHITZERT, a citizen of the United States, residing at East Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Machines for Making Barrel-Hoops, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to improvements in machines for making barrel-hoops; and it consists in the construction and novel arrangements of devices, all as hereinafter fully eX- plained, and particularly pointed out in the claims appended.

The annexed drawings, to which reference is made, fully illustrate my invention, in

which Figure 1 represent a front view of my.

device. Fig. 2 is a vertical sectional View of the same. Fig. 3 is a rear view. Figs. 4, 5, 6, 7, and 8 are detail views.

Referring by letter to the accompanying drawings, A designates the main frame of the machine, consisting of the lateral vertical uprights a a, having the vertical guideways aa, and connected to one another by the lower cross-bar, a2, upper bar, a3, and central crossbar, a, which latter bar is slightly inclined upon its upper edge from front to rear, as

shown.

B indicates the vertically-moving carriage, consisting of the vertical lateral slide-bars, which play within the guideways of the main frame, and are connected at their lower ends by a cross-bar, b, and a little below their cen'- ter by the cross head or block b', which latter is beveled on its rear face, and is provided with a cutting blade or knife, b2, which is secured thereto on its iront or face by bolts the heads of which enter countersunk perforations in said blade, thus'permitting the bolthead to be flush with the face of the blade.

The knife-frame is connected at each side to the upper end of a pitman, b3, by a bolt, b4, which has'a vertical movement in the slots b5 in the main uprights. Said pitmen are connected at their lower ends to a crank-shaft, 11G, extending transversely across the lower portion of the machine, and the same ris provided with the drive-pulley b7 and a pinion C, which kto the transverselower bar of the sliding frame To the end of the levend, opposite to the eccentric end thereof, is adjustably secured a block, D, by means of the thumb-screw d, and

pivoted to this block at its lower end is a rod, d, which is also pivoted at its upper end to a tilting frame, d2, the lateral arms d3 of which Venter kerfs made in the cross-bar of the main frame, and are pivoted at their ends therein, as shown in the drawings.

On the front of the machine, and on each side thereof adjoining the main uprights, are secured castings d, to which are pivoted E- shaped dogs or holding devices d5, the vertical arm E of which is curved upwardly and inwardly, and is provided with a spring, e, having the same curvature as said arm, and between said spring and arm is a space, e', in which a stud, fr, plays that is secured to and projects from the ends of the cutter-head, as shown in Fig. l of the drawings. The horizontal arm e2 of the dog extends toward the center of the machine, and is designed to bear upon the plank when the cutter descendsto sever a strip from the plank, and hold the lataforesaid. f

F indicates vertical rods which are pivoted to the rear face of the central cross-bar at f, the

fupper ends of which receive the strip after being-cut from the plank, and support the same in rear of the cutter-head and between the rear incline face of the latter andthe spring-arms f@ which latter arms are secured when said strip is firmly held in position to be pointed, as will be further explained. These rods F are curved downwardly and rearwardly at their lower ends, and are kept in engage` ment with an adjustable arm, f2, which is se- ,ter firm in place and upon the central cross- 8 5 lbar ofthe main frame, and the tilting frame IOO . a connecting-bar, g3, which is cured by va `set-screw to a depending bracket, f, fixed to the lower cross-bar o'f the vertical sliding frame, and can be adjusted at will, in order to have the upper end near or far from the central cross-bar of the main frame in regulating the position of the strip to be pointed.

G represents the knives for cutting the lapping ends of the strip or hoop, which are arranged at each end ofthe cutter-head and below the stripcntting knife, and are provided with countersunk perforations at each end to receive the head of the securing-bolts, by which they are fixed to the cutter-head, and the same are inclined inwardly and set at the desired angle in order to cut the lap-joint of the strip prior Y to the severing` of said strip by the knife b2.

At the rear of the sliding frame,and operating thereon,is the mechanism for pointing the ends of the strip or hoop after the same has been cut from the plank, which I will now explain.

The letters g represent inclined rods, the upper ends of which are securely bolted to the rear face of the cutter-head, and the lower ends thereof are provided with eyes or bearings through which passes a horizontal translverse bar, g', and revolves loosely therein. -Sliding upon these rods g is the block g", that carries on its upper inclined 'face the cuttingknives whereby the strips are pointed. 'Pivoted at one end to each side of these blocks is also pivoted at its opposite end to a crankarn1, g, that is fixed tothe transverse rod or bar g', and about the center of this rod or bar is secu red one end of an arm, g5, which is horizontally slotted at its opposite end, as at g, to receive a bolt, h, which connects the lower end of a vertical rod, H, with the arm g5. The'upper end of this latter rod is pivoted to a short screw-threaded rod, h', that passes through a perforation in the center of the top cross-bar of the main frame, and is provided with a nut, h2, whereby said rod H may be raised or lowered, as circumstances require, in regulating the stroke of the cutters in pointing the strip.

The sliding blocks g2 are provided each with a projection, h3, on the upper and lower faces of which the cutter-blades are bolted, as shown at h, and passing horizontally through this block is a perforation, which extends from end to end thereof. Within this Vperforation is a rod, I, the end t of which projects therefrom between the cutting-blades, and is held in this position by means of a spring, i', secured to the block, and pressing upon the end t of the rod I aforesaid, and the end 'i serves to force the cuttings from the space between the knives after the strip has been pointed. The cutter-head is provided at each end on its rear face with horizontal dovetailed slide Ways s, to receive a correspondingly-dovetailed slide, i4, which is opposite the cuttingknives h, and receive the edges of said knives after the cut is made in pointing the strip, thus preventing said edge from injury, and said slides can be readily replaced when worn and become worthless.

Having thus given a description of the varions parts of which my machine is composed, I will now proceed and lexplain more fully its operation.

Qperati on shaft, revolving the same, ends of said shaft, through When power is applied to the the cranks on the the medium of the pitmen b3, causes the knife-frame to idescend,

when the knife l2 cuts a strip off the plank which has been previously laid upon the tilting frame, and the lapping parts are also cut by the same stroke by means of the knivesG at the ends of the cutter-head b; `and by the rotation of the gear-wheel c, with its camgroove acting upon the fulcrumed rod c, the

tilting Vframe d2 is operated, thus 'feeding the knife, and said plank is held the inwardly-extended arm which latter 'are operated to the knife-head b",

plank to the long firmly in place by e2 of the dogs E E, by the studs w, secured which act upon the 'curved vertical 'arm E thereof, while the spring eserves to allow the dog to yield should a thick vplank be used. After the strip is cut from theplauk said'strip is delivered upon the ends of the curved rods F, being forced thereto by the plank when getting in position for the next cut, when said strip is grasped by the springs f `and Aheld 'in rear of the cutter-head, and between the same and the inclined face thereof, andV when the knife-frame asc'ends, carrying with it the strip, the ends of the same are pointed by thc pointing-knives in the following manner: The 'upward movement of the 'knifefframe causes the block to move forward on the inclined rods g, by means of the crank-arms pivoted thereto by the connecting-rods g,secu'red to the transverse rod gf, which carries the crank-arm g5, connected to the lower end of the verticallyadjustable rod `H,and when the knife-frame rises the crank-arm is forced downward, thus turning the transverse rod'g and forcing the 'knives h* against the 'ends of the strip, thereby cutting and pointing thesalne, and the action of the spring i upon the rod I inthe block g2 forces cut pieces or chips from between said knives, thus keeping them free jto a'ct.

It will be seen from the above description,and

by reference to the annexed drawings,thatthe mechanisms for operating the tilting frame and pointer cutter-knives are adj ustably arranged with relation to one another,t`hus enabling the operator to adj ust the parts to a nicety, in or- 'der to permit the cutting and feeding frame to work Ain harmony, as also the pointingknives.

To the front face of the Avertically-sliding frame, and below thestrip-cuttiug knife, is secured a gage,as'shown, and it will be further seen that the second strip forces the first or preceding strip, after the same has been pointed, out from the spring-clamps, and takes its place to be pointed, and by this construction of a hoop-cutting machine the strip is cut from the plank,for1ned with lapping ends, and pointed, and drops in rear of the machine a complete hoop,ready for the market. At the same time said machine is simple in operation and durable.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. Inalioop-machine, the combination, with the main frame A, having the slideways, and the Vertically-sliding frame B, carrying the strip-knife b'l and lapping-knives and operated as described, ofthe pivoted tilting frame d2, its adjustable connecting-rod d', lever'c, fulerumed to the standard, gear-wheel c, pinion C, cam-groove c2, spring-dogs d5, cutters h4, and means, as described, for operating the same, the rods F, curved at their lower ends,
